LONG-SHAPE SILICA SOL AND ITS PRODUCTION

LONG-SHAPE SILICA SOL AND ITS PRODUCTION

PURPOSE:To obtain a sol useful as a microfiller having improved film forming property without causing precipitation or increase in viscosity even for high SiO2 concn. by modifying the shape of colloidal silica particles which have conventionally a long shape. CONSTITUTION:The silica sol of this inve...

Zusammenfassung:PURPOSE:To obtain a sol useful as a microfiller having improved film forming property without causing precipitation or increase in viscosity even for high SiO2 concn. by modifying the shape of colloidal silica particles which have conventionally a long shape. CONSTITUTION:The silica sol of this invention contains a dispersion of amorphous colloidal silica particles and has 5mmu and
